Bud,
A question, not an argument. On my big block which still has the factory installed pointer the bottom side as I see it has a long sweeping curve and goes down low to a bolt that holds the bottom on. The top side is not flat but angles just a little and the pointer is at an angle \ something like at the bottom of that slash. Everything else is as you say, so maybe I am just getting the idea of a straight top confused. My bottom side is flat but not for a very long distance as that curve comes out about half way. I think maybe I misunderstood just what Paul meant by the long flat side and I hope that my post didn't confuse him any.
